HUGO STRAOHE, OF VIENNA, AUSTRIA-HUNGARY.

VALVE FOR WATER- GAS GENERATORS.

SPECIFICATION forming part of Letters Patent NO. 646,060, dated March27,1900.

Application filed July 21, 1899. Serial No. 724,698. (No model.)

To all whom it may concern:

Be it known that I, HUGO STRAOHE, a sub j ect of the Emperor ofAustria-Hungary, and a resident of Vienna, Empire of Austria-Hungary,have invented certain newiand useful Improvements in Stop-Valves forWater-Gas Generators, of which the following is a full, clear, and exactdescription.

The present invention relates to stop-valves for water-gas generators;andit consists of the details of construction hereinafter set forth, andparticularly pointed out in the claims.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which a verticalsection of the valve is represented in Figure 1, Fig. 2 being ahorizontal section on line A A of Fig. 1.

Similar numerals of reference denote similar parts throughout bothviews.

According to the present invention the closure is not effected bycontact of the surfaces of the valve and valve-housing, but by means ofa sealing fluid, and in addition to the said sealing fluida coolingfluid circulation is also provided for to prevent the vap orization ofthe sealing fluid owing to the great heat to which these valves areexposed.

The valve-housing 3 is advantageously made in two parts superposed, thevalve 1 being vertically adjustably mounted in a suitable stufflng boxand gland in the cover of the upper portion, which also contains theout- 1et pipe 8 for the gas or gases allowed to pass when the valve isopen.

The valve 1 has the form of an inverted cup, the lower rim of whichdepends into an annular groove 2, formed in the housing,

which groove is adaptedto contain the quicksilver or other fluideffecting the closure. The lower part of the housing contains thegasinlet to the valve, as indicated at 7, and is also provided with anupwardly-extending annular mouth 4, which is of such dimensions as toleave an annular passage for the cooling fluid around the passage orgroove 2,

per surface of the sealing fluid, and thus'pre vent the vaporization ofthe same.

I claim as my invention- 1. A valve for water-gas generators having avalve-housing, an inverted cup forming the valve proper, an annularchamber to carry a sealingfluid and into which the lower rim of said cupdips when the valve is closed, an upwardly-extending throat within saidannular sealing-fluid chamber, to form with the valvehousing an annularcooling-chamber within the sealing-fluid chamber and means forcirculat'ing a cooling fluid within said coolingchamber in the mannerand for the purpose substantially as described.

2. A valve for water-gas generators, having a housing, adownwardly-turned cup to form the valve proper, an annular chamber hav-7 ing an upwardly-extending rim located beneath said cup when the valveis closed, said chamber containing the sealing fluid, and an interiorthroat extending upwardly through the space within theannularsealiug-chamher and having its upper edge reaching above the rimof the sealing-chamber and means for supplying cooling fluid to theexterior of the said throat and for conducting off the said coolingfluid at a level above the rim of the sealing fluid channelsubstantially as described.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.
